“…The concept expressed was not in accordance with the existing concept where chlorophyll as a green substance is located not only in leaves, but also in almost all green parts of plants, which are leaves, stems, and fruit (Yudiati et al, 2021). Chlorophyll in plants is located in chloroplasts scattered throughout the plant body.…”

Misunderstanding in drawing conclusions about a concept caused by errors and incomplete thinking is called misconception. The existing misconception can lead to ongoing misconception if it is not immediately corrected. This study aimed to analyze how the level of misconceptions that occured in prospective science teachers. This study was conducted using a mixed-method with an explanatory sequential design. Methods of collecting data were Three Tier Multiple Choice (TTMC) test questions to analyze the misconception and in-depth interview to determine the factors causing misconceptions. The instrument used in this study was TTMC diagnostic test. Technique used for analyzing misconceptions data were descriptive percentages and for analyzing factors causing misconceptions data were in-depth interview. The results show that 60.4% of prospective science teacher students had misconceptions, which means that the misconceptions that occured were in the high category. Factors causing misconceptions were dominated by incompleteness in understanding the material, the influence of previous learning, the references used contain the wrong concept, low interest in deepening the material to find out the correct concept. This study is expected to help teachers and prospective teachers to decide what learning methods can be used to prevent misconceptions. Remediation can be done to find out where the misconceptions occur so that it can be corrected more quickly.

“…The production and content of pigments depends on nutrient availability particularly nitrates and phosphates (Yudiati et al, 2021). Potassium nitrate (KNO 3 ) considerably increased chlorophyll content as compared to other potassium sources because it contains nitrate which plays important role in vegetative growth of plants by improving chlorophyll content (Zhang and Shangguan, 2007).…”

S weet lime (Citrus limetta L.) locally known as Mettah is extremely famous all around the globe because of its excellent nutritional and medicinal properties (Tanaka, 1994). Sweet lime has great demand during Aug-Sept due to its refreshing juice.Along with its importance in juice industry sweet lime is known for its cooling affect in problems like fever and jaundice (Kumar et al., 2020). However, growers are facing yield related problems particularly due to poor cultural practices and the use of inappropriate fertilizers. Among various factors plant nutrition is the critical factor which influence Abstract | Sweet lime has acquired great commercial importance globally particularly in juice and medical industry. However, its poor yield discourage farmers from its cultivation. Plant nutrients particularly Potassium plays critical role in growth and yield of citrus crops. Therefore, for the possible solution the current study Potassium fertilizer source and timing regulate growth, flowering and yield in trees of sweet lime (Citrus limetta L.) was conducted during the year 2019. Experiment was laid out in RCBD split plot arrangement with 2 factors and 3 replications. Potassium sources (Potassium chloride (KCl), Potassium sulfate (K 2 SO 4 ) and Potassium nitrate (KNO 3 ) were applied on different dates i.e., 15 th Feb, 25 th Feb, 7 th March and 17 th March. Potassium sources and its time of application significantly affected various attributes of sweet lime. Among different sources, KNO 3 was more effective in increasing leaf chlorophyll content (46.47 mg g -1 FW), leaf area shoot -1 (135.29 cm 2 ), fruit weight (85.64 g) number of fruits tree -1 (808.75) and fruit yield tree -1 (69.48 kg). Potassium sulfate application decreased days to full bloom (33.58). Whereas the application of potassium sources on 17 th March significantly increased leaf chlorophyll content (44.31 mg g -1 FW), leaf area shoot -1 (127.95 cm 2 ), number of fruits tree -1 (739.52), fruit yield tree -1 (63.68 kg) and reduced days to full bloom (20). Hence it is recommended that KNO 3 must be applied on 17 th March (mid of March) for better growth and yield attributes of sweet lime.

Eucheuma cottonii is a type of seaweed that has been cultivated. Factors that can inhibit seaweed cultivation are weather, and the solution is tissue culture. Seaweed tissue culture requires explants with adequate nutrition. The use of growth regulators and PES fertilizer is expected to meet the nutritional requirements. The research aimed to analyze the effect of the combination of atonic growth regulator and PES (Provasoli Enrich Seawater) media on the growth of Eucheuma cottonii. The research was designed in a method using the Complete Randomized Design (RAL) method with 4 treatments consisting of K (atonic growth regulator 0 ppm and PES 0%), A (atonic growth regulator 15 ppm and PES 1%), B (atonic growth regulator 15 ppm and PES 2%) and C (atonic growth regulator 15 ppm and PES 3%). The seaweed used in this experiment was Eucheuma cottonii with an initial weight of 0,093±0,008 grams and an initial length of 2,08±0,01 cm. The result of this research can increase the growth of Eucheuma cottonii. In conclusion, the combination of 15 ppm atonic growth regulator and 3% of PES in culture media could increase the survival rate, weight-specific growth rate and length specific growth rate of Eucheuma cottonii explant.
